y=6-2x
\n" ); document.write( "2x+y=6
\n" ); document.write( "5y+8x=20
\n" ); document.write( "8x+5y=20
\n" ); document.write( "...\r
\n" ); document.write( "\n" ); document.write( "2x+1y=6 .............1
\n" ); document.write( "8x+5y=20.............2
\n" ); document.write( "
\n" ); document.write( "multiply (1)by -4
\n" ); document.write( "
\n" ); document.write( "-8x-4y =-24
\n" ); document.write( "8x+5y=20
\n" ); document.write( "
\n" ); document.write( "Add the two equations
\n" ); document.write( "
\n" ); document.write( "y=-4
\n" ); document.write( "plug value of y in 1
\n" ); document.write( "we get
\n" ); document.write( "2x-4=6
\n" ); document.write( "2x=10
\n" ); document.write( "x=5
\n" ); document.write( " \n" ); document.write( "
\n" );
